I am sure you guys understand this, but the conversation goes over my head very quickly. So use small words if possible.
If I am shooting with a 12 mp camera (Canon XSi) and I know it's set at it's largest format (jpeg, not RAW). What file size in MegaBytes should I expect to see?
I am thinking, "Am I wasting the mega pixel abilities because it's just compressing everything anyway when I shoot in jpeg mode?"
Thanks and Happy Thanksgiving to all.
